More specifically, the left-leaning trio has said they agree
with Trump's call to close the so-called "carried interest" tax loophole,
which allows hedge-fund managers and other wealthier
Americans to pay lower taxes on incomes through capital
gains.

Though Trump has not released a plan detailing the
specifics of his proposed tax reforms, he has suggested raising
the capital-gains tax repeatedly, claiming that the profits
that hedge fund managers make should be taxed like real income.

"They're paying nothing, and it's ridiculous. I want to save the
middle class," Trump
told CBS' John Dickerson in August. "The hedge-fund guys
didn't build this country. These are guys that shift paper around
and they get lucky."

"They're making a tremendous amount of money — they have to pay
taxes," he added, saying hedge-fund managers are "getting away
with murder."

The message resonated with Warren, who praised Trump's
suggestion in an appearance on "The View" on
Tuesday.

"Donald Trump and I both agree that there ought to be more
taxation of the billionaires, the people who are making their
money on Wall Street,"
Warren said.

And in an interview with Bloomberg on Tuesday, Buffett, the
Berkshire Hathaway CEO, also said that he agrees with
Trump's suggestions on tax policy.

"For the issues the Bush campaign is using to attack its
unexpected nemesis are precisely the issues on which Mr. Trump
happens to be right, and the Republican establishment has been
proved utterly wrong," Krugman said.

A push to close the carried interest tax loophole, long a goal
for Democrats, has been gaining steam on the right in recent
months.

Bush, for example, unveiled his plan to reform the tax code on Wednesday.
Though it includes plenty of cuts aimed at pleasing the
Republican base and attempting to drive economic growth, Bush's
plan also proposes closing the carried-interest loophole.
